I've got a login page that uses username and password in TypeScript.
export interface UserLogin { email: string; password: string; } //OR export class UserLogin { email: string; password: string; }
How do you know when to use what?
A class is a blueprint of how objects are supposed to be implemented, whereas interfaces are used only for type-checking.
In your case, it would be right to use an interface for UserLogin.
